proximately the reverse of the supplying process except that the starting temperature T3 is lower than T2. Consequently T4 is lower than T[. During the low pressure quiescent period that follows the exhausting process, the gas element absorbs heat from the adjacent tube wall and moves from position 4 to 1 due to the slight expansion of the gas being heated by the tube wall. When it arrives in position 1, its temperature gets once again in equilibrium with the temperature of the tube wall at this position. Thus the cycle is finished. It can be seen that during this cycle the gas element takes h..................[:=> Show Contents <=:]

The externally imposed boundary conditions are a cyclically moving piston wall at one end of the tube and constant temperature or heat flux boundaries at the external walls of the hot end and cold end heat exchangers. The experimental method to evaluate the optimum parameters of OPTR is difficult. On the other hand, developing a computer code for CFD analysis is equally complex. The objectives of the present investigation are to ascertain the suitability of CFD based commercial package, Fluent and also to examine the performance for th..................[:=> Show Contents <=:]

flow through the regenerator. This decreases the refrigeration power per unit of compressed mass and therefore increases the regenerator loss. The larger the mass flow rate in the regenerator is, the smaller the effectiveness of the regenerator will be, and the larger the pressure loss will be. Both of these effects cause a reduced performance.

d to schedule a time frame for eliminating their production. This agreement is a historic step in the on going process of building consensus regarding environmental impact of CFC. Both the Montreal protocol and provisions for 1990 clean Air Act specify schedules for phasing out CFC production by year 2000.
This forced a new wave of research and development in refrigeration technologies. Existing technologies are being adapted to new chemicals, processes are being refined to become more energy efficient, and innovative approaches to refrigeration are being tested.
